If an input is set as unterminated, that input must be looped to
a terminated video device using the lower BNC connector (see
Looping Video Outputs, page 2).

Coax Code Selection

The AD1202 provides two different types of code output for
coax control to a camera Receiver: Standard or Enhanced
UTC code. The selected code is transmitted to the camera
Receiver, via the video coax connection, encoded onto video
signal line 17 during the vertical interval.

Select the type of transmitted code (Standard or Enhanced
UTC) by pin 23 (Code Select) on the EXTERNAL connector
(see page 3).

To Transmit Enhanced UTC code, leave pin 23 on the

EXTERNAL connector open.

To Transmit Standard UTC code, connect pin 23 to Ground

(pin 16, 22, or 24) on the EXTERNAL connector.

OPERATION

Controlling Camera Site Functions

Camera site control functions (pan/tilt, motorized lens, preset
scenes, and auxiliary actions) are available using the AD1202
front panel buttons (Figure 7) after a camera input is selected.
Select a camera either manually from the AD1202 front panel,
or externally from a compatible AD switcher, depending on the
Camera Selection mode.

Note: Only one method of selection is enabled at one time.

See Camera Selection, page 6, to set the AD1202
camera selection method.

CAMERA SELECTION AS A COAX CONTROLLER

When the AD1202 is set as a coax controller, select a camera
from the AD1202 front panel by pressing the corresponding
Channel Select button for the desired camera input number
(1 - 4).

CAMERA SELECTION AS A CONTROL FOLLOWER

When the AD1202 is set as a control follower, the AD1202
automatically selects a camera in response to an external
switcher camera selection.

A compatible AD switcher must be connected to the
AD1202 EXTERNAL connector binary inputs (BIN IN
pins) (see CONNECTIONS, page 3). When a camera is
selected by the switcher, the camera address is provided via
the BIN IN pins and the AD1202 automatically selects the
camera input programmed for this address.

The monitor output of the switch should be used to view
the selected inputs.

Note: The AD1202 must be programmed for the camera

numbers used by the connected switcher (see
Camera Programming, page 6).

Camera Pan/Tilt Control

Camera pan/tilt units are controlled by the four AD1202 front
panel arrow buttons.

To control camera Pan and Tilt:

1. Select the desired camera (manual or external selection).

2. Press and hold the front panel pan/tilt arrow button in the

desired direction.

For control of variable-speed pan/tilt units, camera
movement speed may be selected via the pan/tilt buttons.

• Press the outer side of each button (larger arrow) for fast

movement.

• Press the inside of each button (smaller arrow) for slow

movement.

Note: To obtain diagonal camera movement, press two of the

arrow buttons simultaneously (e.g., left and up, right and
up, etc.). Be careful that you press each key either over
the small arrow or the large arrow. Pressing all four key
switches (two key switches on each key) simultaneously
will result in no camera movement on the diagonal.

Release the button when the camera is at the desired scene
or view, as shown on the monitor.

Camera Lens Control

Camera motorized lens units are controlled by the AD1202
front panel IRIS, FOCUS, and ZOOM buttons.

To control camera motorized Lens functions:

1. Select the desired camera (manual or external selection).

2. Press and hold the front panel button designating the

desired lens action (Iris OPEN or CLOSE, Focus NEAR or
FAR, Zoom TELE or WIDE).

Note: The available lens control functions depend on the

type of motorized lens installed on the camera (e.g.,
an Auto-Iris lens cannot be controlled by the IRIS
OPEN or CLOSE buttons).

3. Release the button when the camera lens is at the desired

Iris, Focus, or Zoom position.
